Energy Band Creator

STEP 1: Discrete Energies in an Individual Atom

Begin by determining the energies of single atom represented by a rectangular potential energy diagram.  The opening screen of the program shows a default potential energy well (Depth = 100eV, Width = 0.1nm).

STEP 2: Energy Bands in Solids -- Multiple Atoms

Having observed the energy levels of a single atom, investigate changes in these energy levels when several atoms are brought close together.

STEP 3: Creating Impurity States

Add impurity atoms to the "Regular Solid" by clicking on the "Impurity" tab.  The screen  of the program shows the default parameters of the impurity atom (Depth = 100eV, Width = 0.1nm).
